$namespace = openstack.common
The subcommand documents for $namespace were hardcoded and thus prone to
drift over time. This commit removes the hardcoded content and uses the
autoprogram-cliff directive to generate them automatically from the
subcommand configuration classes.
This incorporates a correction to `openstack versions show`: The command
`openstack versions show --help` showed a copy/paste error, using
<region-name> for the metavar for both --service and --status. Fix.
